tag_summary = "The remote host is using a version of mod_ssl which is
older than 2.8.10.

This version is vulnerable to an off by one buffer overflow
which may allow a user with write access to .htaccess files
to execute arbitrary code on the system with permissions
of the web server.

*** Note that several Linux distributions (such as RedHat)
*** patched the old version of this module. Therefore, this
*** might be a false positive. Please check with your vendor
*** to determine if you really are vulnerable to this flaw";
